Why do I have no energy at all?

You don't have enough iron and vitamin B12... I know you said that you got your blood drawn, but did you get vitamin B12 checked as well as iron?? you need BOTH for energy! you might want to eat some spirulina (sold at health food stores). it's a superfood that has alot of the B-vitamins in them and I personally have ALOT more energy once I eat that.
